Cardinal Mountain (13396') via Taboose Pass 4.12-4.13.13

An out-and-back overnight trip - Taboose Pass Trail to Cardinal Mountain. Close to 17 miles round-trip with 8000' gain/loss. My first trip of the season to the Sierra. Day One was about 6 miles with 4000' gain. Day 2 was about 11 miles with 4000' gain/8000' loss. New lens - I need to learn more about aperture settings.
